Top one is a Bushmaster lower with Magpul PRS stock, Sierra Precision Rifles grip, CMT upper, Bushmaster 20" HBAR with custom compensator by RJ's Custom Shop out of Washougal, WA, and a Bushmaster Varminter freefloat tube. The scope is an IOR Valdada 2.5-10x42. I don't think I will have enough room to mount the scope, and will either have to get a Larue mount or add some rail section to the freefloat tube or replace the tube with a rail system. I cut down the original front sight tower to make a low-profile gas block. I don't think I will keep it, it looks pretty bad. Next step is a JP trigger.
